Harvestmen of Canada

Abstract

Harvestmen are the third largest Order of Arachnida. Biological information, other than morphology used for taxonomy, is very limited. Canada has at least 43 species, mostly Euponi (Caddidae 3, Phalangiidae 12, Sclerosomatidae 17). Nine species are Dyspnoi (Ceratolasmatidae 1, Ischyropsalidae 2, Nemastomatidae 3, Sabaconidae 3). Only two are Laniatores (Triaenonychidae). Six species (mostly Phalangiidae) are probably introduced from Europe. Distributions and life history information will be given for selected species.
